LONDON--Copper prices rose to a one-week high on Monday as the dollar weakened and traders refocused on supply disruptions at mines in Chile and Indonesia.

The three-month London Metal Exchange copper price rose 0.97% to $5,789.50 a metric ton in midmorning trade in Europe.

Gold prices were also higher, gaining 0.32% to $1,208.46 a troy ounce.

Over the weekend, the union at Escondida--the world's largest copper mine--rejected efforts by BHP Billiton, the majority-owner of the mine, to restart talks. The strike has now been running for more than a month.

Those renegotiations are unlikely to restart before new Chilean labor regulations go into force at the start of April that could affect future negotiations, according to David Wilson, an analyst at Citi in London.

"It's quite obvious that Escondida is going to go on for a while," said Mr. Wilson.

On Friday, a strike at the Cerro Verde mine in Peru, which is owned by Freeport-McMoRan Inc. began. A dispute over the terms of an export license for Freeport's Grasberg mine in Indonesia also continues to drag on.

Prices for both base metals and precious metals were also gaining on the back of a weaker dollar on Monday, as traders awaited a busy week of market news ahead of a potential rate increase.

The WSJ Dollar Index, which weighs the dollar against a basket of other currencies, was down 0.13%.

The Federal Reserve will meet on Tuesday and Wednesday, and are widely expected to raise rates for the first time this year, while offering cues on the timing of future rate increases this year.

Among the base metals, aluminum was up 0.29% at $1,886.50 a metric ton, lead was up 0.69% at $2,276.50 a ton, zinc was up 1.40% at $2,747.50 a ton, nickel was up 1.61% at $10,080 a ton and tin was up 0.75% at $19,360 a ton.

Precious metals also advanced. Silver was up 0.12% at $17.05 a troy ounce, platinum was up 0.09% at $943.85 a troy ounce, and palladium was up 0.36% at $750.75 a troy ounce.
